A diagnostic tachometer must be used for this pro-
cedure.

1. Start the engine and warm it up for a few min-
utes at approximately 1,000 to 2,000 r/min.
Occasionally rev the engine to 4,000 to
5,000 r/min. The engine is warm when it
quickly responds to the throttle.

lead, and then set the idle to the specified
idling speed by adjusting the throttle stop
screw. Turn the screw in direction

to in-
crease the engine speed, and in direction
